ARTHUR B. ROBINSON, OF DIOIINSON, NORTH DAKOTA.

PHONOGRAPH APPARATUS.

SPECIFICATION forming part of Lettere Patent No. 691,000, dated January 14, 1902.

Application filed January 14, 1901. Serial No. 43,200. (No model.)

To @ZZ whom t may concern:

Be it known that I, ARTHUR B. RoBINsoN, a citizen of the United States, residing at Dickinson, in the county of Stark, State of North Dakota, haveinvented certain new and useful Improvements in Phonograph Apparatus, of which the followingis a specication.

The invention relates particularly to coincontrolled multiple-record apparatus, which may be of the general character shown in my Patent No. 634,025, dated October 3, 1899, or of other types to which this invention is applicable either in the special form herein disclosed or in other forms capable of producing like results and which may no doubt be readily devised by those skilled in such matters without departing from the principles of my invention. The general purpose of the invention is to prevent the movement of the reproducer into working position until a record has been properly placed in cooperative relation to it and to prevent the record While the reproducer is in action from being moved or shifted.

In the accompanying' drawings l have indicated an apparatus like or the same as that disclosed in my patent above mentioned.

Figure l is a Vertical section on the line 1 l of Fig. 2; Fig. 2, a plan view of one side of the machine with one of the side plates or standards of the frame in section, and Fig. 3 a detail sectional view on the line 3 3 of Fig. 2; Fig. 4, a detail plan View showing the reproducer and its actuating and controlling mechanism; Fig. 5, an elevation of the lefthand end thereof; Fig. 6, an elevation of right-hand end; Fig. 7, a detail elevation, partly broken away, indicating the reproducer and some associated parts; and Fig. 8, a detail section in the line 8 8 of Fig. et.

Ais the disk carrying the multiple records B, and O its shaft, to which the spring D is applied, the organization being such that the shaft may be drawn outwardly and it and the disk rotated to bring either of the records into cooperative relation to the reproducer, all as fully disclosed in my patent.

E is the ordinary rising-and-falling or rocking reproducer, and F the ordinary rocking shipping-trough, controlling the up-anddown position of the reproducer,

In apparatus of this kind there is danger of the reproducer being thrown forward at a time when a record is not in position to receive it, a condition liable to result, by reason of the subsequent rotation of the reel or group of records, in injury to both the reproducer and one or both of two adjoining records. There is also liability of injury both to the reproducer and records should the shaft be manipulated in an attempt to turn up a new or adjoining record while the reproducer is in operative contact with another one. Broadly speaking, the invention consists in means for preventing the occurrence of either of these conditions. Such means or mechanism may of course be embodied in various forms. That which experience has demonstrated to be a suitable, practical, and efficient one is shown in the drawings and is as follows: Coupled to the ordinary shippingtrough, which rises as the reproducer descends, and vice versa, by a pin-and-slot connection G, is a lever H, pivoted in rear of such connection, as in a bracket I, and whose rear end 7L extends over the shaft C. In the shaft is an annular groove c, with which the end of the lever engages. VVheu the shaft C is in its normal position, the lever enters the slot as lthe reproducer moves into operative relation to a record B and locks the shaft against end- Wise movement. Should the shaft not be in normal position when the reproducer is moved forward, the end of the lever abuts against an ungrooved part of the shaft and arrests the forward movement of the reproducer. In the construction shown the bearing-box K of the shaft is slotted at 7c, and the end of the lever is guided in the slot. When the shaft is in normal position, the annular groove therein is opposite the slot. A usual construction of apparatus of this general character is shown in Figs. et to 8.

L is the winding-shaft, on which is secured the gear Z, which meshes with the gear Z" of the usual spring or weight motor.

M is the coin-chute, and Ml M2 M3 the 1e- Vvers or latches associated therewith and with the ratchet-wheel N and which permit the operation of the winding-shaft.

The reproducer support or carriage E is mounted on the sleeve E3 and guided below by the part E4 on the shaft E2. The sleeve E3 slides on the longitudinally-slotted sleeve IOO O, which incloses the usual screw feed-shaft I M3 and move ,it until the lug lm5 has carried '13. The lower part EL of the reproducer carriage or support is of hollow construction and contains the feed-block e, which is engaged by the spring e and actuated by the cam-piece e3. This mechanism is of usual construction and is clearly shown in cross-section in Fig. 8.

Mounted on a stud-bearing on the right- 4hand upright of the machine is the toothed wheel Q, which is so located'that a pin Z2 on the winding-shaft can engage with its teeth. On the wheel Q are two pins q and q, which engage with the latch R and with alugf on the end f of the shipping-trough F. This trough is normally drawn down by the spring]CA2 and held by a latch R, controlled by the spring r. The trough F is pivoted to the end frame by screwfs. In the trough is a spring S, which returns the reproducer and its connected parts to their normal position at the left-hand side of the machine after a composition has been rendered.

At the left-hand side ofthe machine are located the above-mentioned latches or levers M M2 M3 and the ratchet-wheel N. The lever M is pivoted at m and hasl a pawl end m, adapted to engage the ratchet-wheel N, and having a pin m2, that is partially encircled by a'lug m3 on the upper portion of the lever Mz, pivoted at mi. Also pivoted at m4 is the lever M3, which has a projecting lugm, adapted to work against the edge of the free end of the part M2.

The operation is as follows: When a coin is deposited in the coin-slot M, it depresses the lever M andv disengages its pawl end m from the ratchet-Wheel N. The coin, however, is not allowed to drop past the lever M', as the pin m2 on the lever is prevented from continuing its upward movement by the lug m3 on the latch M2. The winding-shaft can now be revolved in the direction. indicated by the arrows in Figs. 5 and 6. The wheel Q is re,- volved by the pin Z2 on the winding-shaft engaging with its teeth until the pin q, mounted thereon, engages the lug f/ and raises the trough F, that carries with it the cam-piece e3, which permits the feed-block E4 to engage the screw feed-shaft P, and also permits the reproducer-carriage to drop the reproducer upon the record. The screw feed-shaft P engaging the feed-block causes the reproducer to feed across the record against the tension of the spring S. During the reproduction of the record the winding-'shaft revolves in an opposite direction to that shown by the arrow and carries around tooth by tooth wheel Q in a direction opposite to that indicated by the arrow thereon. On the first revolution of the winding-shaft now occurring the pin 'n' on the ratchet-wheel N will contact with the lever the latch M2 to such position that its lug m3 has passed out of the way of the pin m2, thus permitting the coin to carry the lever M' down and fall into a receiving-box, (not shown,) when the lever M will return to its normal position. The winding-shaft continues to revolve until the pin q on the wheel Q contacts with and disengages the latch R from the trough endf, at which time the spring]2 will return the trough to its normal position. The trough F will carry with it the cam-piece e3, which lirstraises the reproducer and then disen gages the feed-block from the screwshaft. The spring S now pulls the reproducer and its associated parts to their normal position at the left of the machine. An adjustable stop and buffer O/ is provided to lessen the blow of impact.

I claim as my inventionl. In a multiple-record phonograph apparatus, the combination with the multiple-record carrier, reproducer and screw feed-shaft with which the reproducer is engaged when lowered and disengaged from when raised, of a locking mechanism operated by the raising of the reproducer to lock the multiple carrier when in a normal position against manipulation.

2. In a multiple-record phonograph apparatus, the combination with the multiple-record carrier, reproducer and screw feed-shaft with which the reproducer is engaged when lowered and disengaged from when raised, of a locking mechanism controlled by the upand-down movement of the reproducer, and acting either to preventthe descent ot the reproducer if the carrier is not in a normal position, or on the descent of the reproducer to lock the carrier if it is in a normal position.

3. In a multiple-record phonograph apparatus, the combination of the multiple-record carrier having an endwise-movable annularlygrooved shaft, the rocking reproducer, the screw feed-shaft with which it is engaged when lowered and from which itis disengaged when raised, the rocking trough controlling the position of the reproducer, and a locking-lever actuated by the trough to either enter the groove and look the carrierif in a normal position when the reproducer descends, or to abut against the shaft and prevent the descent of the reproducer if the carrier is not in a normal position.
